Does anyone out there know what generic type of chip is used in AdLib and SoundBlaster boards? How about any other synth chips that are designed for computer interfacing (low external component count required)? I'm thinking about playing around with synth chips, and this would really help. I can't be happy just buying one of the boards... I'll want to expand, and improve it as soon as I get bored with it! I would like to start with one of the above chips, in case I do want to use some existing software... Thanks a M -Chris thebes!max!chris

I think they use DSPs like the TI32000 series, in which case they would be mask programmed and not readily available. I have hacked a board which can be used to read the contents of a programmed 32010/11/15 so you could in theory copy those chips, but that is rather naughty. If you are looking for really nice sounds, a DSP based system would be the way to go. It however means you will have to design a fair bit of hardware and software. DSP code is not entirely pleasant. You can find quite a few analog type sound chips like the one used in the Commodore 64, the 6581 SID chip. Connecting it to your PC could be interesting and I don't know how much hardware hacking you want to do. cheers Teik.

Somebody already answered about DSP chips.
The "C/MS chips", standard in older SBs and essence of GameBlasters
were Philips SAA1099, very easily interfacable with a PC bus.
